ANSYS Workbench

ANSYS Workbench is a project-management tool. It can be considered

level interface linking all our software tools.

Workbench handles the passing of data between ANSYS Geometry / Me

Postprocessing tools.

This greatly helps project management. You do not need worry about t

files on disk (geometry, mesh etc). Graphically, you can see at-a-glance

project has been built.

Because Workbench can manage theindividual applications AND pass

data between them, it is easy to

automatically perform design studies

(parametric analyses) for designoptimisation.

File Location on Disk

Should you need to identify the individual files on your disk for each sta

project, these can be found by enabling View > Files. The resulting tabl

reference the directory and filename with the project cells.

Use of Archive / Restore

Working with Parameters / Refresh an To make changes, you can manually open up a component cell (e.g. geometry)

You then need to update your model. From Workbench you can choose to then u

Summary

ANSYS Workbench is a convenient way of managing your simulation p

Workbench is used to launch the individual software components, and

transfer data between them.

It is easy to see at-a-glace how a model has been built, and determine

were used for a particular simulation (pairing geometry files to solver

Workbench also makes it straightforward to perform parametric analy

the user needing to manually launch each application in turn), and masimulate multi-physics scenarios like fluid-structure interaction.
